Original applicationled September' 16, 1924, Seria1 10,`737,656. Divided and this application filed March 9, 1925.

This application is adivision of our coending application, Serial No. 737,656, filed eptember 16th, 1924. g

It is the customary practice. in the manufacture of water gas to use a plant consisting of a generator, carburetor and superheater, together with a wash-box or seal, through which the gas from the plant passes and which prevents the return of the gases once' they have passed therethrough.

Until recent years, -it has beenA the practice to pass steam directly into the generator at either the bottom or the top thereof when making gas, the' former instance being called an up-run and the lattera down-run. vIt has recently been customary in many plants, however, to pass steam directly into the super-heaterin order to make what is called a back-run. It is to thislatter type of plant that our invention is directed.

Our construction embodies primarily the positioning of a single swinging valve between the port leading from the super-heater to the wash-box and the port leading from the generator tothe Wash-box, so that either of these ports may be closed by thesimple movement of this single valve at the same time the other port is opened. Our construction, furthermore, utilizes a swinging valve operated by the same means which operates the first mentioned valve, for directing the passage of steam either through the superheater or through the generator. And, further, the blower pipe passageway -to the gas plant generator is at cert-ain times utilized as apassageway for steam into the generator, aswell as a passageway for gas from the generator.

Among the objectsjoi our invention, therefore, are the Aprovision of .a .single valve' which may be more quickly reversed than two independent valves', with lthe consequent reduction in cost because of the smaller number-of valves used, as well as reduction of time required to open and close the valves; the constant lclosing of the back-run line except during that portion of the cycle when back-run gas is being made with the con.

sequent prevention of hydrocarbon vapors backing up into the back-run line, condensing out and filling the back-run pipe Serial No. 13,968.

With 4a tarry or itchy deposit; the elimination of the possi ility of one valve sticking or failing to work while another is open; y

the positive assurance that steam will be directed through the port through which it is intended to be directed because of the connection of the steam valve with the main valve; the reduction in the amount of steam Apipe used; the provision of an open passage perheater stack cap so as to eliminate any 1 as t0 prevent passage of steam to the Wash- I box during the back-run operation.

.With these, and other objects, in view, our invention consists of the arrangement, combination and construction ofi the various parts of our improved system as described in the specification, claimed in our claims and shown in the accompanying drawings, in which:

Fig. 1 is a side elevation of a embodied in our invention..

Fig. 2 is a plan view of the same.

Fig. 3 is a detail view, partly in section, of the main double acting valve utilized in our invention.

Fig. 4 is a detail view showing said valve from another angle.

We-have shown a gas plant consisting of a generator 5, a carburetor 6, a super-heater 7, and a wash-box 8. The customary fuel opening-9 for the generator, oilspray opening 10 for the carburetor, and stack cap 1l for the superheater are shown more or less diagram- 'matically, inasmuch as they form no part of our invention.

Suitableconnections for the various elements are provided' as in the conduit 12 gaf plant leading from the generator to theearburet or, theconduit 13 leading from carburet- "or tothe super-heater ,and the ofitake conduit let leading Afrom ,the super-.heater 4the passage 18 intozth Q Y Y 1,605,081

' ing `a flared and rounded seat 21- at approxi# mately the crest of the yoke. A bolt 22 lex? tends through this seatl having the head threof bearing against the inner face of the yo e.

A pair of separated plates 23 joined together at approximately their centers by a web having a rounded portion 24, are secured to the yoke 20 by reason of the bolt 22 extending through the rounded portion 24, so as to cause one portion thereof to bear in the seat 21 and the other portion thereof to bear in aseat 25 provided on the end of the bolt 22 and secured in place by the nut 26 on the end of the bolt. l

One end of the shaft 19 is provided with va lever 28v connected with a shaft 29. Arms 30 'connect the shaft 29. with a hydraulic piston contained inthe c 'linder 31.-

. It will-be noted tha the-aperture throul h the-portion 24 is of larger diameter at t e outer edges thereof than at the center so that the bolt 22 bears against the sides of the aperture at substantially' one point only, t usjpermtting'universal movement .of the portion' 24 and likewise lthe plates 23. The

'shaft 19 is soipositioned in the housing 15 whilefwhen t e shaft is moved in the oppo- -site directionthe'lother plate 23 will engage that when it is rotated in one direction, one

of the plates'. 23 'willengage the mouth Aof the vertical '.ortion of the passageway 14 the face ofuth'e horizontal portion of the passage 17.'-

For thev introduction of steam into the sysltem, we utilize 'a passage 32, which communicates with the passages 33 and 34, the passage"33leading into the assage 14 and the passage-34 leading4 into t e'passage 17. A double acting valve is positioned at the junc- 4cnnected by the passageway 38 with a 'suitable source. of water supply. The ring 37 is perforated and a constant supply'of water v1s carried therethrough with the result that the plates.- 23fllare` constantly being supplied withmater so'as to 'Prevent the collection of foreign matter thereon. The excess water drips from 'the plates 23 down into the washbox 8 so as'to constantly maintain a suflicient supplyof water therein.

The passage39 is utilized for blasting, be-

ing connected with the generatorfthrough the'l1 passage18. vWhen the blasting is-*dlscontinued, the valve-40 is closed so as to permit theuse of the passage 18 for other purposes. v

It will thus be seen that in making an uprun?, steam is passed. through the passages *'32, 34, 17 and 18 into the bottom of the generator and gases are 'carried from thetop of the generator through the passage 12 into vthe carburetor 6, through the passage 13, in'

'tothe superheater 7 through the oiftake 14 andthe housing 15 into the wash-box 8.A During Ithis operation, the plates 23 are .in

such' position as to close the housing l5 to the' passage' 17, as shown in Fi 1.

In making -a back-run, ge hydraulic cylinder 31 is operated so as vto reverse the plates 23 andclose the passage between the housingl and the assage 14, at the saine timel closing, throug the valve 35, communication between thepassage 32 and 34 and permitting steam entering the passage 32 to be' directed through the passage 33 into the off-take 14 from whence it follows through the super-heater 7, the passage 13, the carburetor 6, the passage 12 and the generator' into the passage 18 and thence through the passage v17 intothe housing 15 and 'thef It will be noted that with-the foregoing construction, all of the objectsmentio'ned are accomplished and avhighly efficient gas plant provided.

It is obvious that various changes may b e made in the arrangement," combination and construction ofthevarious parts of our improved device without departingfrom the spirit of our invention, and it is 'our inten'- ion to cover by our claims such changes as may be reasonably included'within the scope thereof.

What we claim is: 1. A valve of the class describedcomprising a pair of plates, a webA having a knob at approximately the center thereof joining"- v i 11o apertured ball seat on the crest thereof ing a housing, an arched-member having an swingably supported within said housing," a

pair of oppositely vfaced plates positioned within said housing, .a ball for securing said platestogether, said ball having an aperture therethrough-tapering inwardly to form-a constricted opening in the'center thereof, a

bolt inserted through 'said apertur'edA Aball ,seat on said arched member and'through said 1 ball connecting said plates for movably se-l curing said plates to said archedmember.

5 3. A valve, comprising'a housing, a pair of oppositely facing plates in said hous1 n'g, a ball connecting said plates having an openios-l ing therein of`smaller diameter at the center of said ball than at the circumference thereof, an arched supporting member having an apertured ballseat on the crest thereof swingably secured in said housing, a bolt extended through the ball seat on said crest of said supporting member and through the aperture in said ball5 and a'second'ball seat adapted to fit on the free end of said blt and against said ball for movably secur- 10 ing said plates. and said ball to said bolt and to said arched supporting' member.
